Interestingly, the cytokines IL‐1β, IL‐2, IL‐4, IL‐5, IL‐6, IL‐7, IL‐9, IL‐10, IL‐12A, IL‐12B, IL‐13, IL‐15, IL‐17A, IL‐18, and IFN‐γ and the chemokines CXCL9, CXCL10, CXCL13, CXCL17, CCL11, CCL19, CCL17, and CCL22, which are known to be stimulated by bacterial infection, were highly upregulated in HEK‐blue hTLR2 cells stimulated with C. tertium HGMC01 cells. The gene discussed is CCL22; the disease is bacterial infectious disease.
